GMR50 – Compact High Power Shunt Resistors with Improved Heat Dissipation for Space Saving Automotive and Industrial Applications
ROHM has introduced a new series of shunt resistors named as the GMR50 series delivers an industry-leading power of 4W rated power in a compact 5.0mm x 2.5mm size. The new series has combined a revised electrode structure with an optimized device design to improve heat dissipation in the PCB where the resistor is mounted, this results in a 39% smaller mounting area compared with the conventional 4W products.
Feature of GMR50 Shunt Resistors
- Rated Power: 4W
- Resistance Ranges from 5mΩ to 220mΩ
- Temperature Coefficient: ±25°C
- Operating temperature: -65 to 170°C
- Industry’s highest rated power along with improved durability under overcurrent loads
Note: More Technical details about the GMR50 shunt resistors can be found in the datasheet linked at the bottom of this page.
The GMR50 series can sustain overcurrent loads and deliver stable current detection accuracy even when unexpected loads exceeding the rated power are applied, contributing to improving reliability in system level. These devices are ideal for current detection in motors and power supply circuits used in automotive systems and industrial equipment.
